History

De Edensermolen was built in 1847 to drain the Breeuwsma Polder. It was restored in 1958. A new pair of sails were required to replace those damaged in a storm. A secondhand pair were fitted, bringing the cost of the restoration down from an anticipated ƒ765 to ƒ485. The mill was sold to Stichting De Fryske Mole (Frisian Mills Society) on 13 October 1977. In 1995, it was restored to full working order. In 2006, the mill was officially designated by Wetterskap Fryslân as being held in reserve for use in times of emergency.

Description

De Edensermolen is what the Dutch describe as an grondzeiler. It is a two storey smock mill on a single storey base. There is no stage, the sails reaching almost to the ground. The mill is winded by tailpole and winch. The smock is covered in horizontal boards, while those on the cap are vertical. The sails are Common sails. They have a span of 10 metre. The sails are carried on a wooden windshaft. The windshaft also carries the brake wheel which has 32 cogs. This drives the wallower (17 cogs) at the top of the upright shaft. At the bottom of the upright shaft, the crown wheel, which has 26 cogs drives a gearwheel with 25 cogs on the axle of the Archimedes screw. The axle of the Archimedes screw is 250 millimetre diameter. The screw is 750 millimetre diameter and 3.8 metre long. It is inclined at 24°. Each revolution of the screw lifts 114 litres (25.1 imp gal) of water.
